Patent JP-S647377-A (JP)
Title: Digital phase control circuit
Inventor: TAMURA KATSUSHI
IPC: H03L7/08
Filed: 1987-05-29
Abstract: PURPOSE:To obtain a phase control circuit with high reliability by averaging a phase difference between several sets of input information and an output clock and limiting the mean value into a proper value so as to attain a phase correction value. CONSTITUTION:A referencing circuit 11 receives reproduction information 101 to generate a signal 103 for one period of a clock 102 synchronously with a reference clock 102. A phase difference detection circuit 12 detects a deviation of an output clock 104 from an ideal position at a period of the clock 102 to discriminate the lead/lag depending on the sign of the output 105. A selection circuit 13 gives an output 105 to registers 14, 15 for each signal 103 and the registers 14, 15 always keep the phase difference between the bit of two consecutive sets of reproduced information and the output 104. An averaging circuit 16 averages a stored value together with the sign and a phase correction limit circuit 17 limits the output of the averaging circuit to + or -2. Through the constitution above, even when the direction of phase deviation in the consecutive 2-bit information is inverted, the correction of the phase deviation of the preceding information does not directly give an effect to the succeeding information and the synchronization is not lost and the tracking is attained.

Abstract: PROBLEM TO BE SOLVED: To surely turn of a DC/DC converter by preventing the self-exciting oscillation of the converter when its main circuit is stopped, by connecting a fifth switching element in parallel with a fixed-width switching element and sequentially controlling each switching element. SOLUTION: A fifth switching element Q5 and a control means 30 are provided in parallel with one of two fixed-width transistors Q3 and Q4.

The current of an inductor L2 is reset and becomes '0 (zero)' the voltage drops at a diode D3 connected in antiparallel with the transistor Q3 and at the fifth switching element Q5. Thereafter, the converter is surely stopped by preventing the self-exciting oscillation of the converter by giving turning-off signals to the transistors Q3, Q4, and Q5.

Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To output an RSSI signal high in precision with a simple configuration without providing an expensive and complicated additional circuit corresponding to an automatic gain control(AGC) means of the digital control system. SOLUTION: A signal from an A/D converter 14 is given to an integration section 15, a voltage or a power component resulting from taking an absolute value of or squaring the amplitude component is integrated for a prescribed time. The integrated value is compared with a prescribed reference value at an RSSI output section 16, and in the case that the integrated value is a prescribed reference value or over, the RSSI output section 16 outputs an RSSI signal. A demodulation section 13 upon the receipt of the RSSI signal establishes code synchronization with an output signal from the A/D converter 14 and demodulates the signal to recover data.  On the other hand, in the case of transmission, after confirming the RSSI signal not outputted from the RSSI output section 16 before the start of transmission, processing such as spread spectrum modulation, frequency conversion and filtering processing is applied to data and the processed data are transmitted.

Filed: 1994-05-27
Abstract: PURPOSE:To demonstrate that a total organic carbon meter has the sensitivity for measuring ultra low concentration by diluting external pure water with ultrapure water according to a ratio calculated at a sample injection control section thereby preparing a test liquid having ultra low carbon concentration. CONSTITUTION:A working curve representative of the relationship between the total carbon (TC) concentration and the output from a detector is determined for a standard liquid and held at a working curve section 30. A specified quantity of general pure water is injected to a TC oxidation reaction section and a value measured at a data processing section 13 is compared with the working curve held at the section 30 in order to calculate 31 the TC concentration of pure water. The pure water is then diluted with ultrapure water (condensate of steam produced at the reaction section) based on the TC concentration of pure water thus calculated and a ratio for diluting to a preset ultra low carbon concentration (about 50ppb or less) is calculated 32. Subsequently, the quantities of pure water and ultrapure water are calculated based on the dilution ratio and a desired ultra low concentration test liquid is prepared and injected to the TC oxidation reaction section thus demonstrating that ultra low TC concentration can be measured.

Filed: 1985-06-25
Abstract: PURPOSE:To make it possible to cook good rice regardless of skill, by filling rice grains in a plastic container having many small holes and boiling the container and all in hot water. CONSTITUTION:Rice grains 5 are filled in a plastic container 1 having many small holes 4, and the opening part 6 is sealed by heat fusion. The container 1 is then boiled in hot water. The rice grains 5 in the container 1 fill the internal volume of the container 1 due to the swelling, softening and gelatinizing with the hot water and receive pressure bonding action of the container 1 to push out free water between the rice grains 5 from the small holes 4 of the container 1 into the hot water. The rice grains 5 are cooked to give suitable good cooked rice. Thus, the maximum internal volume of the container 1 is designed as a limited volume to apply a pressure suppressing the free expansion of the cooked rice when the rice grains 5 are cooked. Thereby, good rice can be readily cooked by anyone regardless of skill.

Title: Separation of gadolinium or zirconium isotope and apparatus therefor
Inventor: WATANABE JUNKO
IPC: H01S3/03
Filed: 1995-06-05
Abstract: PURPOSE: To improve the efficiency of separating odd nuclear isotope, such as 157Gd or 91Zr, which is the isotope to be enriched from even nuclear isotope by exciting the most of the target isotope to an upper level by adiabatic inversion excitation by irradiation of metal vapor flow with a laser beam and expelling the resonance excitation of the non-target isotope. CONSTITUTION: The metal vapor flow is first irradiated with the pulse laser beam subjected to frequency sweeping so as to cover all of the resonance light absorption lines of the odd nuclear isotope including the resonance absorption lines of the even nuclear isotope. After both these isotopes are once subjected to adiabatic inversion excitation to the first stage excitation level, the resonance light absorption line of only the even nuclear isotope is irradiated with the pulse laser beam subjected to frequency sweeping, by which only the even nuclear isotope is dropped from the first stage excitation level to the base level. Only the odd nuclear isotope remaining in the first excitation level is excited and ionized by the further irradiation with the laser beam.  As a result, only the odd nuclear isotope which has an ultrafine structure and is hardly excited is efficiently selectively excited.
